JTo all 'who/m it B it knowirthatl, Fnaxii J. llLrroire'rria'- va'citzen of the United States; resid-ingat Milwaukee, in'the county of Milwaukee andl 5'State .otWisconsiin haveinvented certain new vandliiseful Improvements in Pneumatic Cleaners, of which thefollowing isa speciication, reference bei :hadto the accom` panying drawing, foriningapart thereof.

-The `n'iain oblets of' this invention' are to etiectively vcleanse; -floors, carpets, walls I [and other-V objectsA by directingaconned bllast or current ofair. or other'iluid which may-@or .may -not be -charged with cleansing L pri-disinfectng substances, 'over .fthesurfaces Ajgfesneh objects, and to catclr and continef'or remove thedust and dirt .ftaken' lup without allowing it..to be .dissipatedand to' settle :again upon fthe-,Surfaces from which it has 'It'eonssts incertain novel .features of construction end 'in-the peculiar arrangement and .combinations of .parts `hereinafter parclaiins.

veniently 'cast inthe forni ot' an oblong box open at the top and having on its under side I nels may be varied.v for instala-e,` as fol- .low s.:0neor more blast channels or cleaning grooves may be provided, and these may be made straight or sinuons as shown in Fig. 12, and arranged more or less transverse to the travel or movement ot' the cleaner. as shown in Figs. 2, 7. and 11, provided vthat theworking face of the base is spanned or .traversed by one or more channels.` Each channel may vbe made to 3 extend entirely across the base, as shown in Figs. .2 and 7. or

a series of shorter channels, as shown 'in Fig.

11 may be used with the-'saine effect, each of the shorter channels overlapping or extending by the adjacent channel or channels, Vso as to cover a transversespace equal to-the length of the longer channel or chan nels','or tothe ividthfrom. end to end of the working faceof the cleaner.

The arrangement of channels or grooves .shown in Fig. 2 Ahas been found in practice convenient and effective. ln this arrangementtivo blast channels ai'e arranged paral lel with each other and slightly oblique to the transverse axis ot the cleaner, and the intercepting channels are both connected at opposite ends ofthe cleaner with-"one end of each blast channel.

A tubular bail d is pivoted in the ends of with or without other detergent, cleansing.

or -disinfecting substances.r to the cleaner. The bail d is provided on each side of its fluid supply connection-with a cock or valve g, by which the supply .of air or other-cleaning a ent to each nozzle .is regulated or cut- "oi l bviously asingle controlling and regulating valve might be provided in the fluid supplyco'nnection f, but this would not afford meansof regulating and cutting ott' the supply of compressed air or other cleanlng agent to each blast -channel iudependently ot' the other channel.

The interce )ting channels c joi'ii he blast 5 channels 7; a jacent to the nozzles e, and at their junction therewith are preferably directed the same wa)1 as thc nozzles, solthat the jet of air or gas issuingr from each nozzle will act as in .an ejector todraw 'air or gas 1S from the channels 1.'. At their ends opposite the blast nozzles the channels b communicate witlrupturned passages h, which open later ally into the ends ofthe box or chamber ou the upper'side ofthe hase or body a above its bottom, as shown' in Figs, l and 3.'

A dustpan or receptacle z',- whichmay bc convenient y made of sheet metal, is removably fitted inthe body or base a. and is provided 'at thevends with openings registering (with the openings at the upper ends of the passages L. Above theseolwnings the dust {eceptacle is provided .with a device for sepaating,r the dust from the dust laden air and permitting the air freed from dust, to escape freely. For this purpose a. zigzag strainer j.

- and a plain -screen of coarser mesh` may be employed.' -The sereen`.7;, -which may be' made of wire,- issupported horizontally by an in- 'w'rdly procting ledge iu the pan or re- 301ccpta`cle1',"a vc lthe`openin' x fs from the pas- 11; The zigzag strainer consists olf c 0th stre hed back'an'd forth over two rows v of lternaing parallelbars Z,n a frame m,

which svremovably'jtted inthetupper part S5-ofthe dust pan or receptacleabove the screen k.f -,'At itsV ends thev strainer cloth is fastened .and held snugly against the ends of the-frame m. as shown in Figs. 1 and 5. by".

rods n, inserted in hems ofthe'cloth and en- 40 gaged with books o on the ends ofthe frame.

At'its sidesthe cloth is held in place against 'the' ls'idej of the framem b v cords n` drawn through-hems o' in the cloth and into notches or depressions yin the ends of the bars l, as

shown in Fig. 6. The cleaner may however,

be provided with other air straining devices,

or the ,dust-laden air may be otherwise vdis.- posed of. *f

ln the operation of the cleaner constructed '50' as hereinbefore described, compressed air or other cleaning agent' being turned on and the valves or'cocks r/ geopened', the cleaner/.is moved and forth over the surface of the carpet or. other object ,to be cleaned.

Blasts oxstrong crrentsfof air or ga's'bciug' directed bv thel'nozzles across-the surface tobecleangd, and ecutned andfitensicd by --the channels or grcovesb la. take up dust and; dirt on the surface exposed to sald chaunels'j and carry them-*upward throunli .the passages h into the receptacle inn( erneath the screen and strainer, which separate the dust and dirt from .the air, and permit the air- .t o --freely escape.' The larger particlesof 'dirt are caught by the screen k, which isof 4marser mesh than the .strainer cloth, and are thus prevented -from entering and lodging inthe spacesY between the folds -ot the strainer' cloth and thereby clogging the same. The strong blast or current produced by the 70 nozzles in the channels I(/entrains ordraw air from the interceptine channels 0. tending to produce a vacuum' tierein, so that dust and dirtwhich might otherwise escape from thc b la-stchannels or cleaning -grooves?) and. be -blown`into the room, are caught in said interccpling channels and returned into Said blast channels. l v' l'nder some conditions, as'fexample when strong air blasts are used, and'thebase 80 of the cleaner forms with the'sur-face'to be' cleaned a comparatively tight closure around the channelsor grooves in said base, a sutii` rient vacuum will be produced' in the intereepting channels c tofprevent o r interfere with the free movenientlof the cleaner.,- .To A oln'iale' this, the blast channels b are re,- `slrieted more or less at or` nc"a1"th`eir outlet ends. as shown at p indfigs. 1, 2 and 3. This restriction or obstruction'of' the blast chan.- 90 nels causes sume air "to escape from each of said channels into the intercepting channels r. thereby foruiing between said'cha'nnels'a thin film ofjair 'on l'which -thc base'of the sweeper rides and' mores with the greatest. 95

freedom. vi While for general cleaning )urposescom` pressed air is usually employe other elastic fluids or gases may he used, and 'for certain purposes such as cleaningwindows or hard flocrs. the airor other gas may be. charged with detergent, abradiiig."polishino' orrdis- 'infecting substances f' i* Referring to Figs. T to- 10 inclusive, showingr another form in which myfinxfention lua)v be embodied, the intcrcepting 'chaunels or grooves n do not. connect with the blast channels Zi', but communicate at both eudsfthrough upturned passagcs" witl 1 the dust catchingreceptacle ab'oye the bottom 110 thereof, as shown in Fig. 8. In other re- -sp'ects the apparatus is lsuhstantiall the same. as that. hcreinbefore describe and shown in Figs. l to 6 inclusive, except that in.-plaee of the two valves or cocks g g, a Asingle regulatinn and' controlling .valve ,or cock r/ is provi( ed in the tubular arm or handle f-of the cleaner, as shown in Figi 10,

In Fig. l1, two slightly oblique blast. cha'nf nels'Zr 63 are shown, overlapping or extend- 120 ing a short distance by, each other attheir il'lner-ends. where they, conitnunicnt with `'upturued passages or opening p ln Fig. 1Q a sinuousor tortu us blastchaunel Zf" is shown as extending aerglssL-thc base 12;'1 with a blast nozzle 'e at one cnd'andaI discharge opening i, at the otl u1.f, .A
